Allow HTTPS connections with self-signed certificates


I am creating an ionic app which uses HTTPS. The application will be used in an isolated environment which means it will have no internet connection. The SSL certificate will be self-signed or issued by an internal Certificate Authority.

Currently in the release build, the HTTPS connections will abort even after installing the certificate as a user certificate.

We are using Angular HttpClient to do the requests and running the app on Nougat (v7) and above.

What is the correct way to resolve this issue?

I am facing the same problem in ionic v4. I have changed the Network security configuration using Cordova to the following:

<base-config cleartextTrafficPermitted="true">
        <certificates src="system" />
        <certificates src="user" />

This should lead to user certificates to be included since in the default config(> Android 7.0 (API level 24) see here) they are not included. But still, my https request fails. Using chrome I can access the corresponding site which uses the same certificate. The certificate is installed as a user certificate in android but does not seem to get to the angular HTTP client.

My configuration:
“cordova-android”: “7.1.1”,
@ionic/angular”: “^4.1.0”,
@angular/http”: “^7.2.2”

My solution seems to work now. I think I caching issues before. Can be closed.
